ive got a rock river 16 inch stainless bull barrel that has a gas block with rail it has 2 set screws in the bottom and i dont see a pin through it anywhere i need to take it off to pull the free float handgaurd so i can put a sling swivel deal on to mount a bipod . i cant seem to get it to move are they locktighted on or what . do i need to pull the pin that goes to the gas tube or that should just pull out with it right . ive pulled them on my smith m/p and didnt have this much trouble . any help would be appreciated thanks
